Vantage Toyota

While undertaking work with Blackburn and Darwen Council, Peak Associates have worked with Vantage Toyota in Blackburn and Colne, achieving savings of over £7,000/year from April 2012. This has led to further investigation work for KFC in Colne and The Rocket Centre in Blackburn, targeting similar levels of savings

Toyota Blackburn was part of a newly built retail park, which included a Lookers Vauxhall site and a The Rocket Centre motorbike sales. The initial view held by United Utilities was that all properties at this site discharged into a communal system in the access road and ultimately into their public surface water sewer in the main road.

However, by investigation of the site layout and drainage plans Peak Associates were able to identify two key flaws in this argument:

Firstly the location of the site was lower than the main road. This meant that the sewage from these sites had to be collected and pumped in to the public main. For the surface water to have been collected this would either need to be a combined drainage system or have a separate pump. On investigation there was no evidence that either of these situations existed.

Secondly, the site had a brook running through the site, and importantly lower than the properties, that was a more likely discharge route. Peak Associates were able to undertake a full drainage survey of this site, securing substantial savings for all three businesses.

Subsequent to the above works, Vantage Toyota also asked us to review their site in Colne. At this site we again determind that there was a brook at site, unfortunately at first glance it appeared to be upstream of the property and therefore United Utilities were charging for the full site draining to the public sewer.

However, our investigation of the historical mapping for this area identified that the brook previously turned and crossed the retail park in the direction of the Toyota site. By checking this against the local sewer information and on site inspection of the drainage system, Peak Associates were able to determine that the watercourse still took this route, but now ran under the Toyota site in a culvert. Our investigation proved a discharge to this, which remains a watercourse, and therefore the charges were eliminated by United Utilities.
